Roush 2011-2014 Mustang 3.7L V6 Cold Air Intake Kit (#421240)
Give your Cyclone V6 the breath of fresh air it needs with the Roush 2011-2014 Mustang 3.7L V6 Cold Air Intake Kit (#421240). This system is one of the most cost-effective ways to increase horsepower and torque without a custom ECU tune. By replacing the restrictive factory airbox with a high-flow, open-element filter and a custom-moulded induction tube, this kit significantly reduces intake restriction, allowing your engine to perform at its peak.
The heart of this kit is the premium washable dry-element filter, which provides superior filtration and greater surface area than stock paper filters. The included heat shield is designed to seal against the hood, blocking out hot engine bay air and ensuring only cool, dense air reaches the intake. Beyond the performance gains, you’ll enjoy a much more aggressive induction sound under acceleration, letting everyone know your V6 means business.
Performance Highlights:
-
No Tune Required: Engineered to work perfectly with the factory calibration for an immediate bolt-on power boost.
-
Increased Efficiency: Higher airflow improves throttle response and can yield fuel economy gains.
-
Reusable Filter: A high-flow dry filter that does not require oiling and is easy to clean for long-term use.
-
Premium Build: Includes a custom-moulded cold air box, EPDM rubber couplers, and all necessary stainless steel hardware.
-
Simple Install: Can be installed in under an hour with basic hand tools.
